We know he was looking into ways to commit suicide. Thats also something the investigation has told us. We know he had mental elt issues as well. Certainly if it turns out that indeed he was practicing this with an airplane full of passengers that of course makes the premeditated nature of all this just so much more clear. Certainly very scary, right, fred . Easy to say its going to be tricky to prove. Stay with us and bring in mary schiavo, former Inspector General for the u. S. Department of transportation. Mary lets try and understand this a little bit. Fred reports there were changes in altitude and this earlier flight that this copilot and pilot took. What does that mean and how much of a range of change could you have without sending off Warning Signals . Well thats exactly right, chris. The Warning Signals would have come in many forms. For example, to change your altitude in this very busy corridor the eus extremely busy in terms of flights in those areas they would have had to have gotten permission from air Traffic Control. Presumably that the pilot was in the cockpit there would have been some reason for doing this. If it wasnt an aerognat kal reason air Traffic Controllers did not ask you to do it then there would be some sort of concoction why this fellow would want to do it hed want to practice his descents and climbs. It should have set off alarm bells if it was done repeatedly. Im going to do this do that. He didnt have a lot of hours, 600 hours. Presumably he could have had a cover story he wanted to practice but it is very strange. Ordinarily you fly your assigned altitude and stick to it in your most direct way to your route. Mary let me put your understanding and freds reporting on the same question. Fred the obviously questions going to be why would you have to practice crashing . Have you figured anything else out from the reporting yet about what is their suspicion, their informationfueled suspicion that you would need to rehearse this . Where do they get that . Well its a very good question. And certainly one of the things theyll be looking at is was he trying to do this in a way that maybe it wouldnt have been noticed that quickly. It did appear when the initial descent started on the doomed flight that it took the captain a little bit of time to find out in the situation that hed been in. Hed been locked out of the cockpit, the plane was in a descent, that obviously would be fatal. In the end was he trying to give himself as much time as possible to cover everything up . Those are questions the investigators are looking at. However, the report that by the way has just come online and we are going to go through it at this point in time this interim report it states more facts. Its less about making assumptions. But it is something that states a lot of fact. Were going to look and see how clear it is whether or not he did practice that during that flight. Certainly it seems as though there were some very very interesting things happening even on that outbound flight that this newspaper says could very well indicate that he was trying to test the waters in all this. All right. Helpful. So mary more information. Reuters is saying that the report is out and that it shows that the pilot ignored a dozen contacts from authorities during the illfated flight which makes sense hed be ignoring it. But also that he set the autopilot to 100 feet five different times during the earlier flight. What does that mean to you . Well thats very alarming. While youve got a plane load full of passengers and put your autopilot to 100 feet again over a very busy corridor in europe theres just no reason to do that. And you have to wonder what was the pilot doing presumably the pilot in command was following this. And that flight he wasnt out of the cockpit. And if he was out of the cockpit and the b. E. A. Report will have all this in it that theyve just released whether or not the pilot in command was present, he was out of the cockpit and went unnoticed thats highly significant and that to me would be very very suspicious that indeed it was practiced. If he was in the cockpit presumably theres a cover story. But that makes no sense at all. You just wouldnt do it. While it is a window into the madness of this copilot help us understand why would you need to practice crashing . Well you know even september 11 hijackers back 2001 the september 11 2001 hijackers they did walkthroughs. They walked around new york city. They had gps. They did lots of various practices. They scoped out everything. They didnt do it just on one day and there was, you know weeks and months and years of practice. So for him to do this to see if he could do it how much time it would take for him to descend the plane, check the rate of descent, check what the plane felt like as he put it into the descent to see if perhaps he could get this plot going without the pilot in command being out of the cockpit actually noticing. So there certainly are reasons to practice such a heinous crime. That doesnt surprise me that one would try to do that. Slow to spread blame. Certainly slow to condemn. But as were learning if all this reporting is accurate and he said it five times hes ignoring these warnings just setting that to 100 feet five times earlier, do you think down the road mary there will be some questions of accountability on what type of watchdog there was on this flight in the air . Right. I think thats probably one of the most important things that can come out of this. And i know the loved ones of the persons onboard would want something to change because of this investigation. So the investigation will be looking for warning signs. What can we learn so in the future when things similar to this happen we know its something to watch out for. And so thats one of the main reasons theyll be poring over every little detail to find out the flags for the future. Right. And on that subject obviously we cannot forget that were talking about his rehearsal. Now potential rehearsal, Mental Illness loomed large here and what happened with doctors and communication and the ability of family to know. Fred youve done so well digging in on that. Anything you learn about the report let us know so we can come back to you. Mary schiavo, thank you very much. Alisyn. Another top story were following, digging into the web of clues left behind two gunmen killed outside that cartoon contest in texas. The attack was more than just inspiration. We go to cnns kyung lah live in the gunmens hometown of phoenix, arizona. What are we learning today, kyung . Reporter isis may be claiming responsibility but officials believe that may be opportunistic. Investigators are scrambling trying were the gunmen simply trying to obtain approval or were they working with that operative to launch an attack . This morning investigators on the hunt for any possible accomplices in the garland, texas terror attack. The fbi scrubbing through the two deceased gunmens Electronics Found in their phoenix apartment searching for any clues that may connect Elton Simpson and nadir soofi to other terrorists in phoenix and across the country. But one Law Enforcement official says investigators did know simpson was openly communicating online with members of isis overseas and even opened a new investigation into both men in recent months. I think from an intelligence standpoint whats difficult is to move that quickly and to arrest him when its not entirely clear that hes going to do it. And we have a lot of people on social media that are saying these kinds of things. Reporter simpson apparently had public exchanges on twitter with this prominent britishborn isis fighter. And a u. S. Born al shabaab fighter in somalia, just a week before the attack simpson tweeted a reference to the controversial event, when will they ever learn. Hasan retweeted his tweet and said the brothers from the Charlie Hebdo attack did their part its time for the brothers in the u. S. To do their part. According to Court Documents hasan traveled to somalia from minneapolis in 2008 to join the terror group al shabaab. And simpson also wanted to joy the jihad in somalia around the same time but it is not known whether simpson and hasan knew each other. This is something that the United States government has been focused on in both of these issues both in terms of foreign fighters as well as efforts that are underway by extremists including those inside isil to use social media to try to radicalize individuals and inspire them to carry out acts of violence. Reporter cnn is also learning that the guns who were that were used in the attack and also were found in the vehicle according to an official with knowledge of the investigation those guns were purchased legally. Back here in phoenix the officials who did scrub the apartment, well the apartment was relatively barren but there was a hard drive recovered. Theyre trying to get some material off of that michaela. Kyung lah, thank you very much. The u. S. Is willing to pay up to 20 million for high level isis targets. The state department announcing huge bounties for information leading to four isis commanders. Cnn Senior International correspondent Nick Paton Walsh has the latest for us live from beirut. Nick. Reporter michaela what were seeing here of course is a bit of a window onto who the u. S. Think are the more important isis leaders. We know they will offer 10 million if someone knows where Al Baghdadi Isis leader is but there are four others now in the frame. 7 million for a man called al kaduli has links back to afghanistan, pakistan and al qaeda in the very beginnings of 2004 and stayed with it during the iraqi insurgency. All that went onto become what we know as isis. Two other names more public a man better known as omar the chechen, hes a key military leader who joined the Syrian Rebels early on and then became more and more extremist to join isis. 5 million if you know where he is. And 5 million if you know where isis spokesman is as well. Hes a very public figure giving many of their statements. And a fourth lesser known for 3 million al harzi. This came out that al qaeda was somehow affiliated or responsibility. I think investigators want to be sure that there are links perhaps to these key leaders and any prior planning of that attack. No sign of that at this stage. There are so many isis fanboys out there on twitter, as theyre known, exchanges messages you talked about. Back to you, alisyn. Thanks nick. Thanks for all of that background. We want to bring in phil mudd to talk about this. Our cnn counterterrorism analyst and former cia counterterrorism official. Phil great to see you this morning. Good morning. One of the gunmen left a twitter trail a mile long. Yeah. He was communicating with isis fighters and calling for violence and just sort of stewing with them online. So what do investigators do with that . One of the challenges you have here is not just to look backward but to look forward. Youre looking at a case can i apply the knowledge i learn from this data to future cases to see if i can prevent this stuff. My answer too is im not sure thats going to work here. The numbers dont help you. 5,700 on average tweets per second going around the universe. And you want to look and sort through those and try to find the person whos not only angry, whos not only tweeting with isis but who might turn a switch and become violent. Im afraid what were going to find here is not just a trail of tweets but a trail of frustration because youre going to say can i come up with a pattern of activity that allows me to sort through the other several thousand cases in the United States to apply the lessons learned. Im not sure what the lesson is. Theres a lot of angry people here and you cant tell which of them is going to switch overnight. One of the clues thats been unearthed by abc news and their Investigative Team is they found he was in constant communication with this mysterious isis recruiter, a guy who goes by the name of miski online. But hes also known as mohammad hasan. And that thats what we just saw in kyung lahs piece where that recruiter said to Elton Simpson, let me read it to you, where are the warriors of this community . Because they were talking about the texas cartoon contest. So where are the warriors the brothers from the Charlie Hebdo attack did their part thats instruction, right . On 911 thats a wholly owned al qaeda plot by what we at the cia call core al qaeda. Trained, directed paid met with the 19 hijackers. If you go forward lets say to 2009 remember the underwear bomber. He met with the al qaeda affiliate in yemen. We go now to 2015 and were talking about terror operations that are not wholly owned by al qaeda, not owned by an affiliate but just a conversation with a guy in iraq or syria who says look i dont need to meet you, i dont need to train you, but the universe of people out there who are interested should feel some obligation to attack. One more comment on this and that is we look at this as a failed attack. That is not how isis would look at it based on what you said. What theyre trying to say is these two guys died in an effort to represent what they regard as the faith. If you dont get out and do the same thing, you should be ashamed that you dont have the courage of your convictions. Theyre going to try to portray this not as a failure but as a success because they inspired people to act. But isnt it a failure . I mean its a pretty spectacular failure. They got out of the car and they were shot dead. Heck no, its not a failure. Phil, you dont see it as a failure either. Just the fact they were inspired from thousands of miles away that means its a success even though they werent able to kill anyone. Correct. I mean when i work at the agency im paid to look at the world through the eyes of the adversary. This is what the adversary thinks. If we cant if we want to inspire a global revolution we cant meet with pay, direct every person who might be part of this revolution. We need simply for them to get the kernel of an idea that leads them to act. If they fail thats okay because somebody one state over or five states over will sit back watch tv in their living room and say, you know, ive been thinking about this for six months and now i feel embarrassed because i dont have the courage to do what these guys did. The other thing id say about this is i always learned to understand what the adversary thinks you might want to look at what they say. If isis were embarrassed by this they would not be out so prominently saying this is ours we own it despite the fact they probably didnt even know who these guys were. This from their eyes is a success because it could lead somebody else to act. Okay. Phillip mudd thank for that insight. Great to talk to you. Lets get to chris. We have more breaking news. This time out of germany. Four suspects there arrested on terror charges.
